What is the main difference between a portable air purifier and a standard room air purifier?

The primary difference is size and capacity. Portable purifiers are designed to be easily moved (often weighing less than 5 kg) and typically cover a smaller area (under 200 sq. ft.) or a localized personal zone. Standard room purifiers are stationary, larger, and built to clean the air in expansive spaces (250 sq. ft. and up), often boasting a higher CADR (Clean Air Delivery Rate).

How often do I need to replace the filter in these portable air purifiers?

For HEPA-based portable units (like OWNAIR or RPM Airtech), filters generally need replacement every 3 to 6 months, depending on the severity of air pollution and how frequently the unit is run. Units utilizing filterless technology, such as the WeFilter Wearable Purifier (which uses negative ionization), require no filter replacement, significantly lowering long-term running costs.

Are portable air purifiers effective against viruses and bacteria?

High-efficiency models equipped with True HEPA 13 filters (like those found in OWNAIR, Airofy, and DNESHY) can effectively capture 99.97% of airborne particles as small as 0.3 microns, which includes many types of viruses, bacteria, and mold spores carried by larger dust particles. Units with additional features like negative ionizers (Airofy, WeFilter) or special composite filters can further target these microscopic contaminants by causing them to fall out of the air.
